To ail whom it may concern Be it known that 1,, JOHN 'J. TATUM, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements n Breke Heads and Shoes, of which the following is a specification.

it is not an uncommon incident in the operation of railroad cars to find that the key which holds the brake shoe to the brake head has become lost and the shoe dropped. The dropping of brake shoes is a source of danger as many cars are derailed by them.

To facilitate the unloading of cars they are frequently run on dumping machines and thereby turned over to discharge their freight-{and in this operation shoe pins drop out of place, thereby releasing the shoe.

The object of my invention is to provides simple bdt.. efiective and economical. way 111 Whichto lock the shoe pin in place against accidental displacement.

A further object of my invention is to provide a brake shoe with a combmed strengthening element and key lock; and with these and minor objects in view my 1n-' vention consists of the parts and con1bina .tion of parts as will be fully hereinafter set forth.

the head. After the shoe has been locked tothe head 1 by the key 5 as shown in F i 1, I bend the extension 4: over the head of the key, thereby locking the key against accidental displacement,- thus exterminating all danger of derailment of the car by dropping brake shoes. 7

As shown in Fig. 4 I may cast a separate piece of softmetal 6 in the shoe to serve as the pin locking member. I may cast a separate piece of soft metal 7 in the'brake head, asshown in Fig. 5 to serve as the lock for the key.

As shown in Fig. 1, the lower end of the.

key 5 may be bent over to lock it in position against accidental displacement. It is a Well known fact that if the brake shoe becomes displaced, it permits the brake head to slip out of the hanger and allows the brake beamto fall on the tracks under the car, which usually results in an accident. Such a contingency is prevented by my invention inasmuch as -the shoe cannot become accidentally displaced. r

I claim 1. A. brake shoe having an end extension constructed to be turn d over a brake shoe key and constitute a lock for said key.

A brake shoe cast with an integral soft pliable end extension adapted to be turned over a brake shoe key, when assembled, and constitute a loclcfor said key.

3. A brake shoe composed of cast metal and a strengthening member embedded in the shoe when cast, said member projecting beyond the end of the shoe proper, the projecting portion being adapted to be bent over a brake shoe key and constitute a lock therefor. i 4. The combination with a brake .head, and brake shoe of a pin engaging and in terlocking said head and-shoe, and a pliable nietal locking member cast integrally with one of the interloc Gd members and adapted. to be bent over the head of the pin to lock it against accidental displacement.
